WIRE-CUTTER.

Application filed July 8, 1918. Serial No. 243,844.

To all whom it may concern:

Be it known that I, CARL BIERNAT, a sub ect of theEmperor of Austria, residing at Glasford, in the county of Peoria and 7 nature of a wire-cutting means which possesses great strength for operating upon' and cutting wires, the device being light in weight and easy and inexpensive to manufacture. j 1 p While these are the main objects of my invention, other objects will appear from the following description thereof in connection with the accompanying drawings forming apart of this application.

In the drawings, like reference characters designate corresponding parts throughout the several views, and

Figure 1 is a side elevation of a rifle provided with my device;

Fig. 2 is a top plan view thereof;

Fig. 3 is an enlarged elevational view of the muzzle portion of the rifle barrel with my invention mounted thereon and illustrated in longitudinal section;

Fig. 4 is a top plan view of the muzzle portion of the rifle with the device shown in longitudinal section, the same being illustrated in its retracted open position with a wire indicated in position for cutting;

Fig. 5 is a transverse sectional View taken upon line VV of Fig. 3;

Fig. 6 is a transverse sectional view taken upon line VIVI of Fig. 4; and

Fig. 7 is a perspective view of the cutting member detached.

Referring more in detail to the drawings, my device may be readily attached to any form of firearm for the cutting of wires and is herein illustrated operatively mounted upon the forward casing or stock portion 10 of the rifle 11, the said rifle having a barrel 12 with a usual form of sight 13 positioned upon the upper side 0 the barrel adjacent the muzzle thereof. A. tube or Patented Oct. 8, 1918.

casing 15 is mounted upon the stock extension 10 longitudinally of the rifle with its open forward end 16 positioned in a plane spaced rearwardly of the plane of the gun sight 13. An anvil or block 17 is secured to the barrel 12 byhaving a perforation in the block opening into a notch 19 of the block, whereby the gun barrel may be slid through the perforation 18 with the sight 13 accommodated in the notch 19. The block 17 is turned upon the barrel 12 until the sharpened transverse. ridge 20 of the block lies in advance of the tube 15, whereupon the bolt 2l-which extends through the portions of the blockat opposite sidesof the notch 19 is tightened for retaining the block upon therifle.

A plunger is provided for the tube 15 consisting of astem 22 anda head 23 adapted for sliding longitudinally within said tube with the stem 22 extending through an opening 24 at the rear end 25 of the said tube. A coiled spring 26 surrounds the stem 22 within the tube 15 tensioned between the head 23 and end 25 and it will be understood that upon retracting the stem 22 the spring 26 will be compressed as shown in Fig. l of the drawings, and upon bein released the forward cutting edge 27 oi the head 23 will violently engage the block 17.

A longitudinal rib 28 upon the head 23 is positioned within a guide slot 29 in the top of the tube 15 which prevents the head 23 from turning and constantly maintains the edge 27 of the head parallel with the cutting ridge 20 of the block 17. Rearwardly projecting lugs 30 are provided upon the block 17 at the upper edge thereof and at opposite sides of the ridge 20 adapted for engaging a wire such as 31 which may be readily hooked beneath the lugs 3Q in a position to be cut between the ridge 20 and edge 27 when the head 23 is projected forwardly.

A rod 32 is attached to the rear end of the stem 22 and is slidably positioned through a ring 33 upon the adjacent side of the stock extension 10, the said rod being adapted to be pulled rearwardly by means of its handle 34: for retracting the said plunger. The soldier holding the rifle 11 may readily retract the plunger head 23 in this manner and then position the rifle barrel 12 beneath the wire 31 positioning said wire beneath the lugs 30 upon the cutting ridge 2O whereupon, the handle 3% being released,

respondingly inclined downwardly wherebythey are adapted for better cutting the ire. 31 therebetvveen, The tube 15 is rigidly seured he st ak extensio 10 by me ns-b screvvs 35 while the'ring 33 is attahd there' to in any desired manner. The' gllide slot;

opens into the end '16 of the tube 15 Whereby a portion of the rib 28 i s-positioned forwardly of-fthe 'ti1be15 when the'head 23 is in its projected Wire'cutting positien altl engh a portion .ei X the rib" 28: still remains Within said slt 29'.
